Abstract
922,836. Semi-conductor rectifiers. TOKYO SHIBAURA ELECTRIC CO. Ltd. Sept. 19, 1961 [Jan. 25, 1961], No. 33578/61. Drawings to Specification. Class 37. A rectifier unit comprises a diffused-junction type silicon wafer having opposite faces of diameter not less than five millimetres, and copper electrodes soldered to the opposite faces of the wafer and each having a thickness equal to at least one-sixth of the diameter of said silicon wafer and a diameter at least equal to that of the wafer. In the embodiment described, Figs. 1-4 and 6 (not shown), boron and phosphorus respectively are diffused into opposite sides of an N-type silicon sheet to form a junction layer therein. The sheet is then plated first with nickel and then with gold before being cut into discs to which copper electrodes are subsequently attached with silver containing lead solder. Threaded bores may be provided in the electrodes.
